There are many electrical kWh watt meters to mount in your fuse and distribution boxes.
What to check before buying one?
S0 must exist (and is almost always there)
Any preferred brands/models? Are there bad one's on E-Bay? (like swissnox, Eltako, DDS or DTS models?)
Thanks.

If you want to be sure that you buy a good kWh meter take one that the power company's are installing in new houses like

thanx,
I mean the small modules that you can plug in the distribution case with fuses. So you can group some places to one meter for example.

I've got a Eltako WSZ12-65A single phase KWh-meter installed. See http://www.hekkers.net/albums/Domotica/ ... index.html
I've had several models, from different manufacturors, all for DIN rail mounting, with S0. They all did what they had to do. In the end i chose one from Eltako's Economy Line; i dont't see the benefit of the calibrated version they also have. +/- 1% is accurate enough for me.
